SpletIn this paper, we present a patient similarity framework (PSF) that unifies and significantly extends existing supervised patient similarity metric learning methods. PSF is a general … SpletApproximation algorithm for PCSF. Klein and Ravi [11] were the first to give an O(logh)-approximation algorithm for the SF problem. Later, Guha et al. [9] improved the analysis of [11] by showing that the approximation ratio of the algorithm of [11] is w.r.t. the fractional optimal solution for the ST problem. The ST problem is a special

SpletOur first main result is a primal-dual O(logh)-approximation algorithm for a more general problem, prize-collecting node-weighted Steiner forest (PCSF), where we have h demands each requesting the connectivity of a pair of vertices. Our algorithm can be seen as a greedy algorithm which reduces the number of demands by choosing a structure with ... Splet22. feb. 2024 · Although the PCSF algorithm itself is able to distinguish most correct homologs by considering the connectivity, we found that by rewarding well-known homologs the noise can be further reduced. The reward parameter 0.5 is chosen such that existing homologs of well-known Parkinson’s genes from our screens are included in the …
